SPECIFICATION forming part of Letters Patent No. 752,449, dated February 16, 1904.

Application filed January 14, 1903.

.T0 aZZ whom it may concern,.-

Be it known that I, JOHN O. GREENWAY, of Ishpeming, Marquette county, Michigan, have invented a new and useful Oar-Unloading Apparatus, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a general front elevation of my Fig. 2 is a top plan view of the same. Fig. 3 is a top plan view of the trolley I employ. Fig. 4 is a general side elevation of the trolley. Fig. 5 is a sectionall side elevation of the supporting and actuating mechanism for the movable head of the device. Figs. 6 andA 7 are crosssections on the lines VI VI and VII VII, respectively, of Fig. 5. Fig. 8 is a side elevation of the mechanism for raising Fig. 9 is an end elevation of the apparatus. Fig. 10, Sheet 1, is a detail view showing the arrangement of the track and wheels for the trolley, and Fig. l1 is a side elevation showingmy preferred form of head. y f f My inventionrelates to the discharging of lump or granular material from dumping-cars, and is designed to assist in this operation by providing mechanism for loosening-the materequires the use of hand labor. -Itis also designed to thaw out frozen material in such cars and mechanically loosen the material at the same time. f

In the drawings I show a traveling bridge having end supports 2 2 ofgeneral-A shape, which carry upper parallel tracks 3 3, preferably formed of rolled channels with their anges 4 projecting inwardly toward each The trolley, which carries the actuating parts of the loosening apparatus, is mounted upon wheels 5, which move within the fianges ofthe channehaseshown in Fig. 10, thus preventing'any lifting of the trolley during the downward movements of the loosening-head. The bridge itself ismounted upon wheels 6 and 6', which travel upon rails i7 7 ,A the bridge preferably being of sufficient length to straddle two or more railway-tracks Serial No. 138,993. (No model.)

i To move the bridge along its track, I preferably provide an electric motor 10, having spur-gearing connection 11 with a main driving-shaft 12 through a combined frictionclutch and brake 13. rIhe shaft 12 is connected ateach end by bevel-gearing 14 with vertical shafts 15, .connected through bevel-gearing 16 at their lower ends with the shafts to which the wheels 6' at one side of the bridge are secured.

Upon the trolley-frame 17 areqnounted two ring-shaped bearings 18 18, within which fit the circular end hubs 19 of a gimbal-frame 20. The central part of this gimbal-frame is provided with circular bearings 21, which receive the trunnions 22 of the vertically-extending guide frame 23, containing a vertically-movable hollow squared shaft 24. The

squared shaft is provided at one side with av series of rack-teeth 25, lwhich are engaged by a pinion 26 upon a shaft 27, supported in brackets 28, secured to the sides of the vertical guide. Y clutch connection 29 with worm-gear 30, conf necting to shaft 31, carrying toothed wheel 32, intermeshing with pinion 33, drivenI by electric motor- 34. This motor is supported upon suitable brackets 35, secured to the vertical guide 23, and is provided with a brake device 36. The worm-gear connection provides for a slow up-and-down movement of the head during its rotation, and to give a more rapid vretical motion to this head when desired-I connect the shaft 27 'at its opposite end through bevel-gear 37 lwith a shaft 38, having clutch connection witha toothed wheel 39, also engaging the pinion 33. 'l By throwing either one of these clutchesthe head may be given a quick reciprocating ymovement or a slow up-anddown movement. This digging and loosening head, one form of which I have shown at 40 in Fig. 1, is secured to a hollow cylindrical shaft 41, which extends upwardly through the hollow'squared shaft 24* and above the vertical guide is splined to a pinion 42,- intermeshing with toothed wheel` 43 kuponthe. shaft lows the shaft 41 to be rotated in any andall The shaft27 has at one end ay positions, while the vertical movement of the squared shaft will impart asimilanmoyement to the shaft-4:1v through the extension. 2.4L on the squared shaft engaging the collar 4:1 on the shaft 4l. If frozen material is being. acted upon, steam or other heated fluid may be supplied through a rotary connection atzthefupf per end of then shaft 41, this V'heated "Huid emerging through the holes 52 at or near the head, as shown in Fig. 11,-and 'thawingeut the frozen material, while the head acts.to...

loosen it.

to the desired point overlthe carszorlthedump.-

cars are moved thereunder, and the trolley ciprocated either'slowly or rapidly te. punch down through and up through thematerial, and at the same timefmay Abe `rotated to.; drill its way downor upor in `both direetions.l fIt is evident th'atfeither orfboth motionsimaybge used at any point desired, and .thershait may be adjusted from time to /timeand `the trolley moved along the bridge, the bridge being moved to bring the tool `throughout all points of the car. The material is thus loosened and the arching or scaffolding broken downand at the same time the frozen mater-ialrmay be loosened by the introduction of heated iiuid.

Instead of the plain drill-head shown in Fig. l, for convenience,-I prefer to use 'an ex-A panding-head of barbed type, one form* of which is shown in Fig. 11. Inthisform the end 47 of theV head is provided with 4al tubular extension 48, having pivoted thereto oppositely-eXtending links 49, connected to inwardly-extending links 50, having loose Vslotted connection with guides 51.

while in lifting the head the resistance will cause the link to open into .the position shown in full lines, thus increasing the size of the hole, and consequently the loosening effect.

The advantages of -my invention will be ap.- parent to those skilled in the art. The us'e of hand-labor, a large amount of which has here.-

. tofore been necessary in loosening' the mate? rial and causing it to slide downthroug-h the bottom openings of the car, is done away with and lthe action obtained mechanically. -The use of motor mechanism is highly `eiiicient in causing the rapid discharge 'of thecar contents, thus effecting a large saving in time-and labor.

` The device lmay be used for loosening the material in either cars, bins, buckets, or other receptacles havingopeningsat or near the In forcing the head down through the material the links l will assume the position shown in `dotted lines,

bottom for discharging it. The mechanism for-actuating. the head lor .loosening device maybe varied@ asweltasthe supporting mechanism, the motors employed, &c., without de- .partingirom my invention.
